Welcome to one of the most beautiful places to race in the Pacific Northwest! The center piece for this epic weekend of racing is Lake of the Woods. Lake of the Woods is nestled 4900′ up in the Southern Cascade Crest. The natural spring fed lake is surrounded by old growth Douglas Fir, Lodgepole and Ponderosa Pines. In the background there is the 9500′ Mount McLoughlin and the 7300′ Brown Mountain, both volcanoes.  We utilize some of the best roads and trails to give a unique, beautiful and challenging experience.

We invite you to stay all weekend.  Bring your friends and family and enjoy all that Lake of the Woods has to offer. There are numerous trails to explore and Volcanoes to climb. You can rent a boat or bring your own boat or SUP to enjoy some time out on the Lake. After the events on Saturday stay for a BBQ and a live band near the bonfire pit.

Family fun includes paddle and motor boat rentals. For a mountain bike experience or fun hiking there is the 9 mile non technical trail to Fish Lake. This trail offers some interpretive signs as well so you can learn about the geological history of the area’s volcanoes.  Come to participate, to cheer on your favorite athlete or just enjoy the quintessential Oregon lake experience!

Cabins will be at the off-season rate, and there is camping at either Aspen or Sunset Campgrounds.  Please visit http://lakeofthewoodsresort.com to get more information.
